EVAPORATOR FOR HOT-AIR PIPES.

Specification forming part of Letters Patent No. 52,572, dated'February 13, 1866.

of Maryland, have made new and useful improvements in evaporators to be connected with hot-air pipes at points between the hotair furnace and registers in chambers, for the purpose ot' supplying moisture to the heated air by the evaporation of water placed in receptacles within the pipes, to be supplied from cisterns or reservoirs situated without said pipes; and I do hereby declare the following to be a full, clear, and exact description ot' the nature, construction, and operation of the same, sufcient to enable one skilled in the art to which it is allied to construct and use the same, reference being had to the accompanying drawings, in which my improvements are shown as applied to a portion of a hot-air pipe.

Figure lis a side view of hot-air pipe A, and front view of eval'iorator-cistern B. Fig. 2 is a front view ot' hot-air pipe A and a side view of evaporating-cistern B. Fig. 3 is a longitudinal section of hot-air pipeA and top view otl evaporating-cistern B. Fig. 4 is a section of the above through the line y z, Fig. 1.

The invention consists in enlarging the diameter ot' the pipe at the point where the evaporator is to be situated, thereby presenting the same area as the connections therewith, so that the introduction of the evaporator within the body of the pipe does not obstruct the equal ow of hot air, and so arranging the evaporator that water can be introduced in it from the outside either by the automatic action of ball and cock attached to the cistern on the outside or by hand.

In the drawings, Arepresents a section ot' a hot-air pipe, with the portion of its diameter enlarged to contain the evaporator B, which may be of metal, in the vform of a rectangular cistern of a size suitable to the dimensions ot' hot-air pipes. This passes through the side of' pipe, as indicated in Figs. 2, 3, and 4, and is connected with a cistern ot' any required dimensions situated at its outer extremities, and to which water is supplied either by the autom atic action ot'a hollow ball or cock or otherwise by hand. There is a slide covering the rectangular part of the evaporator, which, by a rod, can be moved to regulate the surface of the water over which the hot-air passes in its passage from the furnace through the pipes to thev JESSE L. HUTOHINSON.
